Set "Algorithm Type" on the [Vision] tab.
Set "Algorithm Type" to "PTRN Outline" or "PTRN GrayLev".
PTRN Outline : In most cases, select this parameter for pattern matching. When the outline is definite,
the pattern can be recognized even if uneven brightness portions are present inside the
pattern.
PTRN GrayLev : Selecting this parameter is more effective in recognizing a pattern whose brightness is
uniform inside the pattern. This parameter setting requires a longer time to recognize a
pattern than the "PTRN Outline" setting and also data size will also be larger.
PTRN Whole : This parameter is effective when you want to acquire a pattern including its details.
Since the entire pattern is recognized at a lower compression ratio, this parameter
setting requires a longer recognition time than in the "PTRN GrayLev" setting and also
the data size will be even larger.
"Algorithm Type" setting
Set to "PTRN Outline" or "PTRN GrayLev" or "PTRN Whole".
